Hot Rods Bulb Holder for Speedo

Hello,
I'm looking for this style bulb holders to fit the 5/8" holes in the back of my '46 Ford Tudor speedo and clock please. Bulb type doesn't matter but the hole diameter does ...... any help gratefully appreciated.
TIA.

Excellent response, thank you very much ..... you can't beat the HAMB family.
And they're readily available from my regular USA parts supplier.

British Smiths and Jaeger gauges have 5/8” holes. So loads of Jags, Austin, Morris, MG, Leyland cars. Might be easier to find those in Aus.

Think this is the right part number 13H1924

Thanks.
Yes, I was aware of that too.
My original photo was a trimmed version of this LUCAS one. I needed 10 of them and their price made it prohibitive in comparison to the suggested Dorman version from RA for AU$2-39 each.
